The lotus effect refers to self-cleaning properties that are a result of ultrahydrophobicity as exhibited by the leaves of Nelumbo, the lotus flower. [1] Dirt particles are picked up by water droplets due to the micro- and nanoscopic architecture on the surface, which minimizes the droplet's adhesion to that surface.
The leaves of Nelumbo are highly water-repellent (i.e. they exhibit ultrahydrophobicity) and have given the name to what is called the lotus effect. [3] Ultrahydrophobicity involves two criteria: a very high water contact angle between the droplet of water and the leaf surface, and a very low roll-off angle. [4]
The lotus leaves (Nelumbo nucifera) are water-repellent and poorly adhesive which keep them free from contamination or pollution even being immersed in dirty water. This ability, called self-cleaning, shields the plant from dirt and pathogens and plays a vital role in providing resistance towards invading microbes.
Superhydrophobic coatings are also found in nature; they appear on plant leaves, such as the lotus leaf, and some insect wings. [4] This image shows highly absorbent filter paper coated with a super-hydrophobic paint developed at University College London. This repels water (which has been dyed orange for greater contrast)
The contact angles of a water droplet on an ultrahydrophobic material exceed 150°. [1] This is also referred to as the lotus effect, after the superhydrophobic leaves of the lotus plant. A droplet striking these kinds of surfaces can fully rebound like an elastic ball. [2]
It features top notes of green leaves, apple, and lotus that open up to base notes of cedarwood and amber, giving off a cool, balanced musk. Imagine aromatherapy relaxation in a bottle—all ...
Lotus Leaf (5780807820) Unitary roughness structure versus hierarchical structure A lotus leaf is well known for its ability to repel water and self-clean. Yuan [1] and his colleagues fabricated a negative mold of alotus leaf from polydimethylsiloxane (PDMS) to capture the tiny hierarchical structures integral for the leaf's ability to repel water, known as the lotus effect.
